I ended up doing a MANUAL update of QB (Help, QB update, update now), then shut down QB, then restart my computer and relauched QB. Then it worked.
I still had to play quite a bit with the aligment to get the X in the box, but that was more related to the Form by itself than the QB issue.
Hope this helps.
BTW, I have QB Premier edition 2024. Not sure if it matters.
